I was actually considering deliberately making them multiple hues of blue anyway (to account for the variation we see between films and also to make the Jedi seem less stuffy and dogmatic all having identical sabers)

My thinking too, especially the variation part. I still love the way they did them in the original Star Wars. Not a ton of color, just...bright! They look different from scene to scene both in color and intensity. They're supposed to use crystals, so they're not all using the exact same one anyway. Haha.
